Improvement in sofas



FFIon IMPROVEMENT lN SOFAS.

Specification forming partof Letters Patent No. l67.565, dated September 7, 1875; application filed June 19, 1875.

To all whom it may concern:

Be it known that I, THOMAS RAMSDEN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented anew and valuable Improvement in Sofas; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a rear view of my sofa, and Fig. 2 is a front view of the same, showing operation. Fig. 3 is a sectional detail view. 4

This invention has relation to improvements in sofas, whereof the arms are hinged to the bottom, so that one or both may be lowered to form a plane surface therewith; and the nature of the invention consists in combining with a sofa, having its arms hinged to the seat, a vertically-vibrating lever pivoted to the said sofa, and connected with its arms by means of adjustable rods, whereby a reliable and effective means is provided for lowering one or both of the sofa-arms, and converting the same into an agreeable couch, as will be hereinafter more fully explained.

In the annexed drawings, A designates the back, B the seat, U C the arms, and D the legs, of an ordinary sofa, in connection with which I propose to illustrate my invention. The arms G O are hinged in any suitable manner to the bottom or seat B, as shown in Fig. 3, and they are connected, by means of rods E E, to a vertically-vibrating lever, F,

pivoted at or near the center of its length to the back of the sofa, as shown in Fig. l. The lever F is provided with a number of studs, a a, at each side of its pivot b, which studs are arranged at a suitable distance apart, and are designed to serve as points of attachment for the rods E E, which are pivoted at 0 to arms 0 O, and are provided with a number of I spaced notches, n, near their free ends for this purpose. When these rods are hooked over studs a a, the one above and the other below the pivot b of lever F, as shown in Fig. 1, and the latter be then actuated, the effect will be to lower arm 0 entirely, and arm 0 partially, forming a luxurious couch, which may be reconverted into a sofa by reversing the movements of lever F, the arms 0 0 being held in an upright position by the engagement of the end of the lever behind a stop, S, rigidly secured to the rear side of the sofa-back, as shown in Fig. 1. Both the arms may belowered, when deemed necessary, by changing the rod E from its inner to its outer notch 01., in engaging the said rod with the actuatinglever, so that the length of the said rod being increased the degree of vibration allowed to its arm will be correspondingly increased, and the two arms allowed to assume a position in line with the seat or bottom of the sofa.

In practice, this improved sofa may be upholstered in the usual well-known manner, and in lowering the arms its cushions will also be lowered.

What I claim as new, and desire to secure by Letters Patent, is-- 1. In a sofa, having hinged arms 0 O, the combination of the vertically-vibrating lever B and the rods E E, substantially as specified.

2. The lever F, having studs a a, and the rods E E, having notches n, in combination with the hinged arms 0 O of a sofa, substantially as specified.

3. The stop S, in combination with lever F, connecting-rods E E, and hinged arms 0 C, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

THOMAS RAMSDEN. Witnesses:
